Question

PLEASE HELP ME WITH THIS QUESTION
A nail has (1/100 cm²) area at the tip.The force of 100N is applied on it.Calculate the pressure acting on the wall.

Answer 1

Answer:

10^8 Pascal

Explanation:

Pressure = Force / Area on which Force is acting

= 100 N / (1/100 cm²)

= 100 N / (1/100 × 1/10000 m²)

= 100 × 100 × 10000 N / m²

= 10^8 N / m²

= 10^8 Pascal

Answer 2

$\large{\boxed{\underline{\green{ANSWER}}}}$

GIVEN:-

area at the tip of the nail =

1/100cm²

= 1/10^6 m²

Force applied = 100N

TO FIND:-

Pressure acting on the wall.

FORMULA OF PRESSURE:-

$pressure = \frac{force}{area}$

PUTTING THE VALUES IN THIS FORMULA WE GET:-

$pressure = \frac{force}{area} \\ \\ = > pressure = \frac{100}{ \frac{1}{ {10}^{6} } } \\ \\ = > pressure = {10}^{2} \times {10}^{6} \\ \\ = > pressure = {10}^{8} \: \: \: \: pascals$
